Horizontal Electric Dipole

As a result of ship’s corrosion and anti-corrosion in shallow sea, the static electric field and static magnetic field can be produced around ships, which are referred to the static corrosion-related electromagnetic field. In order to analyze the field characteristics, a static horizontal electric dipole which is located in shallow sea is usually adopted to simulate the field. So,the electromagnetic field distribution of the electric dipole is very important because it is the base of analysis. In this paper, some research has been performed on the electromagnetic field of an electric dipole in three-layered conductive media. At first, equivalent source method has been used to derive the distribution expressions of the electromagnetic field in seawater. Then numerical simulation method has been used to do a contrastive analysis of the distribution characteristics of the electric field and magnetic field. At last, some experiments have been done in laboratory to prove the correctness of the theoretical derivation and the simulation analysis. The research results establish the foundation for the further application research.
